Comparison of Pascal and Delphi
Pascal is a programming language devised by Niklaus Wirth in the late 1960s and early 1970s. Originally produced by Borland Software Corporation, Delphi is composed of an IDE, set of standard libraries, and a Pascal-based language commonly called either Object Pascal, Delphi Pascal, or simply 'Delphi' (Embarcadero's current documentation refers to it as 'the Delphi language (Object Pascal)').
